Be it known that I, HOWARD M. BARBER, a citizen of the United States, and resident of Stonington, in the county of New London and Stateof @onnecticut, haveinvented a new and useful Improvement in Sheet Cut and Folding Machines, of which: the following is a specification.

One object of this invention is to provide means whereby a collection of sheets is stitched while at rest and is then: removed I from the stitcher mechanism at a speed less than its feedingin speed, the relative movement of the successive collections being such that the stitched collection is removed at a speed sufficient: to. cause it to clear the next collection asitis fed into the stitcher mecha-. nism, such arrangement permitting the stop page of the collections on the stitcher table a suflicient length of time to allow them to be accurately stitched.

A practicali embodimentof. the invention is represented in the accompanying drawings, in which thatoipart of: a sheet cutting, stitching and folding machine is illustrated which includes my invention. I

Figure I 's' a verticalicentral section taken from front to. rear through the machine.

Fig. 2 is a detail vertical section taken from front to rear just inside the near side frame. i

'Fig. 3 is a similar section takenjust inside the far side frame. I. l Fig. 4E isa detailsection showingthedriv+ ing connection between certain of the parts,

and a Fig. is a detail section-taken just outside the near side frame, showing'thedriv-: ingn connection between certainother of the driving parts:

. Thestitchen table :is denoted by 1-, the

ostitcher. mechanism by 2 its driving shaftby 3,,whicl'1: stitche'r mechanism may i be of any well known or approved construction adapted to stitch collection of'she'ets While the movement of the collection is ar rested. g

The collection transfer cylinder l" is mounted on acshaft 5,'and its set of grippers 6; arranged toineceivera' sheetflfrom an extra source of sheet supply, suclrassa cover i sheetpfrom the table 7 and associate it with a collected *with a folding blade 28, and a group of sheets received from one of'the sets of grippers 8 9, 10 of the collecting cylinder l'l on the shaft 12.

The collectionfof sheets is delivered from the transfer cylinder 4, between two endless tape carriers 13, 14, which endless carriers feed the collections on to the stitche'r table 1, into engagement. with a movable sheet stop 15. A main web is fed by the pair of rolls, 16, 17, through the pair of coacting rotary cutters 18, I9, and throughthe coacting guide rollers 20, 21, to the collecting cylinder 11' and transfer cylinder 4.

In. the arrangement shown herein, the first three sheets of each groupare collected on the cylinder 11, and-these sheets, together with the fourth sheet, are seized by thegrippens 6 of the cylinder 4, which grippers have previously taken a sheet from the table 7. It is evident that one web or a plurality of superimposedwebs.may be fed into the machine as desired, and it is also obvious that a collection of any desired number of sheets may be obtained as desired.

The sheet: stop- 15 is mounted on a rock shaft 22, to which'vis fixed a rock lever 23 having a stud or roller 24: under the control of a rotary cam 25, rotating with the male folding'cylinder 26 mounted on a shaft 27.- This male folding cylinder 26 is provided pair of tumbler actuated grippers 29. The female folding-l cylinder 30 on theshaft 31, carries a pair of folding jaws 32 arranged to-coact with the foldingblade-28 on the male fold i-ng cylinder 26. Any suitable delivery mechanism may be employed for delivering the stitched and folded collections from the female folding cylinder 30, which-delivery mechanism in the present instance, com prises the endless tape carriers 33,-, 34, the dropper delivery 3 5"and the endless delivery carrier 36. a v p I I Spring-pressed rollers 37 are arranged in position to hold the sheet from the extra source of sheet supply in register on the cylinder 4, while the grippers 6 are opened for receiving the'co'lle'cted group offmain web sheets; Springpressed rollers-38 are also provided for holding the group of main web sheets in register on, the cylinder 11', when the-grippers 8, 9' and 10 are open to 1 the spring-pressed rollers 38 are driven from the gear 54: through receive the successive sheets of each collection and to transfer the sheets to the grip L A sheet stop 39 for whichmeans is operatedin any well known,

or' approved manner, the front half of the sheet being associated with one collection of main web sheets and the back half with the next succeeding collection of main 1 web sheets. The web feedrolls 16, 17 are con,- nected to the shaft ,45 of the rotary cutter 19, through the gears 46, 74.7, 48, 49, and'the guide rollers 20, v21, are driven from, the gear 49 throughthe gears 50, 51,, The shaft 12 of the cylinder 11 is connected to the shaft of the rotary cutter 19, through the gears 53, 54. The gear on the shaft 5 of the cylinder 4: meshes with the gear 5st. The spring-pressed rollers 37 are driven from the gear 55 through the gear 56, and

p the gear57'. The'shaft 8 of, the stitcher mechanism is driven through a gear 58 which meshes with the gear 55. The shaft 27 of the male folding cylinder 26 is connected to the shaft 3 'ofthe stitcher mechanism, through the gears 59, 60; A gear 61 on the shaftfl'? meshes with a gear62 on the shaftBl of the female folding cylinder 30. The delivery tape carriers of the dropper mechanism are driven through the gears 63, 6e, 65, 66, 67, 68, 69. The endless delivery is driven fromtheshaft 31,

.- through the bevel gears, 70,71, shaft 72,

worm -73, gears 74, 75, 76.

The relative speeds. of the driving mechanismhereinabove referred to, are such that the stitched collections of sheets arewithdrawn from the stitcher, mechanism at a speed less than their feeding-in speed, ample time beingjgiven for the stitching ofa collection while at rest in the stitcher mec ianism and for the removal ,of'the stitched collection without interfering with the oncoming next succeeding unstitched collection.

The cam mechanism for controlling the floating of the tucking blade and folding jaws in parallelism during the folding of' the stitched collection off from the male cylinder onto the "female cylinder'will notrbe specifically described herein, asit is of well known andapproved' construction and forms no part of the presentinvention; y he objects of having thesheets removed at a speed slower than their feeding in speed are; first, to materially lessen the strain on the moving parts because of this slower speed; second, a greater accuracy can be obtainedtbythe slower speed of the moving the control of a 7 T moved from the" table, of the grippers to slip vention,

parts; third, a lesser strain; fourth, a smoother operation of the parts; and fifth, the advantageous feature of dropping the product on to the delivery belts at a slower speed.

Theslower the stitched sheets are rethe less the liability on the product'and the more accurate'theregister. 7 Bythe term cylinder as used in the description, I contemplate any equivalent means forypassing the sheets and signatures through the prescribed paths and by the term grippers T WlSll to include. any equivalent devices suitable for the purpose of leading the sheets or signatures through said prescribed paths j It is evident that-various changes maybe resorted to in the construction, form and arrangement of the variousparts without'departing from the spirit and scope of my in-;
